Previously, cloning of mirrored images was only supported for primary images. When cloning golden images for virtual machines, this restriction prevented the creation of new cloned images from the golden non-primary image. This update removes this restriction, and cloned images can be created from non-primary mirrored images.	Story Points:	---

Description Sean Cohen 2017-01-11 20:01:38 UTC

In the case of OpenStack Glance, this capability would allow the creation of volumes from a DRed non-primary copy of an image. Proper support would most likely require implementing a deletion "recycling bin" to fix the corner cases with parent/child links and propagating of deletions (i.e. the clone of the non-primary parent image might not be mirrored and the primary parent image would not know about the child on the non-primary side. the primary image could be deleted but that deletion would not properly propagate since the non-primary image would have a child).

Required for OSP 13?
